The photographs shows the wiring of the bicycles for their ride trough
the streets of Berlin in the year 1988.

This piece was first performed in 1978 at Univiversity of Massachusetts,
Boston. Up to 25 bicyces with riders are gathered and each bicycle is
wired up with a self-built pickup device attached to the front wheel, a
self-built battery powered amplifier, a horn-type loudspeaker and a card
or nylon wire tie to pluck the spokes. As the bicycles ride through the
streets, the pitch of the spokes can be heard approaching the listener.
